Highway Safety

Proper highway safety refers to the methods or rules that prevent highway travelers from being killed or severely injured. Proper highway safety measures help to protect motorists, cyclists, pedestrians, passengers on public transport, and so on.

Question

Q1) A rural 4-lane highway is to be built between two towns. Select the binder performance grade
to meet the Superpave criteria for a reliability level of 98%, given the following information about
the project:
Latitude = 46.77
Tair (max) (Seven-day average high air temperature) = 33.1 °C
Standard deviation of the seven-day high air temperature
Tair(min) (1-day minimum air temperature) = -21.3 °C
Standard deviation of the 1-day minimum air temperature = 3.3 °C
= 1.8 °C

Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?

Select the true items related to absorption capacity. Select only the four correct answers. Practical absorption capacity is usually less than theoretical absorption capacity. It is the minimum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour. Absorption capacity depends on the vehicle arrival rate at the minor approach. Practical absorption capacity is usually more than theoretical absorption capacity. Absorption capacity does not depend on the flow of the mainstream traffic. Absorption capacity depends on the flow of the mainstream traffic. Absorption capacity does not depend on the vehicle arrival rate at the minor approach. It is the maximum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour.
